Abstract

Studies of forty-two pregnant women (twenty-one occupationally exposed and twenty-one not exposed) were conducted with the purpose of determining the average values of lead in the blood of pregnant women and their newborns. The levels of lead in the blood were determined using the method of spectophotometry of atomic absorption. The statistical analysis was carried out by SPSS (Statistical Package for the Social Sciences) version 7.5 for Windows, by means of percentages, frequencies, standard deviation and t analysis by the student, variability, lineal correlation and multiple regression. The average values of lead in the blood of exposed pregnant women and those not exposed were from 30.561 ± 6.786 μg/dL, and 19.305 ± 7.376 μg/dL, respectively. The average value of lead in the blood of newborns of exposed mothers was 17.2 ± 5.378 μg/dL, and 4.971 ± 2.868 in newborns of non-exposed mothers. The results of this study prove that significant statistical differences exist in the averages noted above, and that the risk of exposure influences the level of
lead in the blood of newborns and pregnant women, exceeding the permitted levels allowed by the Center for Disease Control in the United States of America. As such, there exists an high and statistically significant correlation (γ= 0.723) between the level of lead in mothers and their newborn infants. The variable levels of lead in the mother is a good predictor of the variable levels of lead in their newborns.
